Evaluation of ultrasonic Flaw Detector measurement uncertainty

The paper "Evaluation of Measurement Uncertainty of Ultrasonic Flaw Detector" by Han Jinsheng from Nanjing Institute of Metrology Supervision and Inspection expounded his specific process of analysis and evaluation of measurement uncertainty of ultrasonic flaw Detector, which mainly combined the actual detection work and based on JJF1059-2012 "Evaluation and Expression of Measurement Uncertainty" and JJG746-2004 "Verification Regulations for Ultrasonic Flaw Detector".
